Hi all,
I would like to monitor the status of my alarm word (MW100) and if any bit turns from 0 to 1 then an alarm signal should be generated, am new to siemens plc and am having a tough time accomplishing this easily. In omrom CX programmer its quite easy to do. Could anyone help me on this using ladder logic, all help will be deeply appreciated.
Regards,
Ablex
PS: I'm using Step 7 V5.5
